Failed Back Surgery Syndrome (FBSS)

Understanding persistent pain after spine surgery and treatment options

What is Failed Back Surgery Syndrome?

Failed back surgery syndrome means you have persistent or recurrent pain after spine surgery. This doesn't mean the surgery was necessarily a "failure"—many causes exist.

Common Causes of FBSS

Continued Pressure on Nerves

  • • Residual stenosis not fully decompressed
  • • Adjacent level degeneration
  • • New herniation
  • • Epidural scar tissue

Spinal Instability

  • • Inadequate fusion
  • • Pseudoarthrosis (non-fusion)
  • • Adjacent segment degeneration

Muscular Factors

  • • Deconditioning
  • • Poor healing
  • • Scar tissue

Other Factors

  • • Complex regional pain syndrome
  • • Central sensitization
  • • Psychological factors
  • • Non-surgical causes missed

Diagnosis

  • History of prior surgery
  • Current pain pattern
  • New imaging (MRI/CT)
  • Comparison to pre-op imaging
  • Provocative testing

Conservative Treatment

Success Rate: 40-60%

  • • Physical therapy (often very helpful)
  • • Pain management
  • • Epidural steroid injections
  • • Radiofrequency ablation
  • • Psychology/pain management evaluation

When Revision Surgery is Considered

  • Identifiable cause on imaging
  • Conservative care trial first
  • Realistic expectations (outcomes lower than primary surgery)
  • Addressing specific cause

MIS Revision Options

MIS Revision Decompression

If residual stenosis or epidural scar

Success Rate: 70-80% (lower than primary)
Recovery: 4-6 weeks

Adjacent Level Surgery

If degeneration at adjacent level

Fusion or decompression as indicated

Success Rate: 75-85%

Revision Fusion or Stabilization

If pseudoarthrosis or instability

Success Rate: 75-80%
Recovery: 6-8 weeks
